WebHeat comes from the sun in this manner and radiates from dry skin the same way. Heat can be removed with liquid from a surface during evaporation. This occurs when a mammal sweats. Convection currents of air remove heat from … WebThere are several mechanisms for heat loss: Radiant heat loss: Bare skin is exposed to an environment containing objects of cooler temperature. Evaporative heat loss: Neonates are wet with amniotic fluid. Conductive heat loss: Neonates are placed in contact with a cool surface or object.
